T cells fighting infection. Computer illustration showing T lymphocytes (T cells, small, green) attacking a pathogen (large, round) in the body. T lymphocytes are a type of white blood cell that recognise a specific site (antigen) on the surface of cancer cells or pathogens and bind to it. Some T lymphocytes then signal for other immune system cells to eliminate the cell. | |
